Mrs. fowler family was going on vacation to Disney worlds. they saved 4500 dollars for the trip. 2/5 of this amount will go to tickets. 1/4 of the remaining money will towards souvenirs and snacks at the park. how much dollars will be spent on souvenirs and snacks at the park.
2/5 of $4500 is (2/5)*$4500 = $<<2/5*4500=1800>>1800.
The remaining amount after buying tickets is $4500-$1800 = $<<4500-1800=2700>>2700.
1/4 of $2700 will be spent on souvenirs and snacks, 1/4*$2700 = $<<1/4*2700=675>>675. Answer: \boxed{675}.
